COUNTERMEASURE APPARATUS FOR DEPLOYING INTERCEPTOR ELEMENTS FROM A SPIN STABILIZED ROCKET

摘要

There is provided a countermeasure defense system against hostile missiles by employing non-explosive intercepting ("NEI") elements 14 deployed by the spin stabilized rocket 10. The NEI are carried in a payload section 17 and contained by a sleeve assembly 16 which is removed by a drive mechanism 21 or a pyrotechnic device 152 after a countdown time delay programmed into the trigger release assembly 46 as controlled by the control unit 150. The drive assembly includes a drive rod 26 that is releasably held by a release assembly 46 a compressed coiled spring unit 30 drives the sleeve assembly 16 forward exposing the payload section 17 to the centrifugal force of the spin stabilized rocket propelling the NEI elements out from the rocket at constant angular velocity creating an interceptor cloud of elements. In another embodiment the pyrotechnic device 152 detaches the shearable screws 170 that secure the payload section 117 from the rocket engine housing 102 thereby setting the sleeve 121 free from the rocket housing 102.
